SPOOL 0F TAPE AND PROTECTOR THEREFOR.

Application filed August 22, 1927. Serial No. 214,690;

The invention relates generally to devices or spools for tape, ribbonand the like, and to their holding elements, and more particularly tospools of surgical adhesive tape or plaster.

Objects of the invention are to simplify and lessen the cost ofproduction and to enhance the eiiiciency of such devices to the end thatthe assembly, the spool-and its complemental holder, will preserve theoriginal aseptic condition of the tape, and so that the spool may bewithdrawn and replaced with facility and dispatch without diminish-ingthe protecting properties of the assembly.

The nature of the invention consists in the provision of a spoolembodying an axial core or center and its complemental end flanges orheads whereof one is a simple disk and whereof the other is formed withan endwise directed flange or rim, and a slip on holder embodying acylindrical shell or casing open at both ends and provided internallywith an annular shoulder which constitutes a stop or abutment for thedisk head of the spool and also cooperates with said head to excludedust and other sources of contamination from the adhesive tape or othercommodity wound u on the spool, the other head performing a 1i efunction through the medium of a friction fit between its rim and theinner wall of the holder, it being understood that slight pressure ofthe thumb upon the disk head will be suii'- cientto overcome thefriction grip and result in the ejection of the spool.

Referring to the drawing, 5 represents a` spool wound with surgicaladhesive ta e 6, and 7 represents its complemental ho der. The spoolembodies an axial core or center 8 formed o r provided at its ends withperipheral anges or heads 9 and 10, the latter having an endwisedirected rim or collar 11.

The mating element or holder is a cylindrical shell whose insidediameter is such as to provide a snug or friction lit-with relation tothe rim element 0f the spool. The shell is formed or provided with anannular shoulder or seat l2, which has a dual function, to wit: toconstitute a stop or abutment for the proximate or disk head of thespool, and in conjunction with the same to seal that end of the spool,the other end being sealed by the friction fit of the rim or collar 11.In short, when the parts are assembled the adhesive tape or othercommodity on the spool is completely sealed by the heads or end flangesacting iii concert with the cylindrical shell or casing.

Evidently slight pressure of the thumb against the disk head of thespool will overcome the friction fit of the rim element and permit thewithdrawal of the spool.

Fig. 3 illustrates an added detail wherein the rim 0r collar element ofthe spool is notched and formed with a knife edge 13 to provideself-contained means for severing the tape. L

Having described the invention, what is claimed as new isl. A spool andprotector assembly, comprising a s ool having fixed heads, and a tubularshel adapted for telesco ic and friction -it with relation to the hea s,and open at its ends to expose the spool to manual pressure to separateit from the shell.

'2. A spool having fixed heads, combined with a separable ring of lengthsufficient to overhang the heads, one end of the ring having a limitingstop or collar to arrest the passage of the spool, and one of the headshaving a Hauge to take a binding fit on the inner wall of the ring` thespool being otherwise free and exposed to endwise pressure to separateit from the ring.

In testimony whereof we affix our signatures.
